From ba78d83be7d04f03a7fe6133efb5b6f83b9b0e7c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 13 Apr 2018 15:40:45 +0200 Subject: gpio: mvebu: Use the proper APIs The MVEBU driver is requesting GPIO descriptors from itself, which is fine, but we have proper APIs to do this in a controlled way, so stop calling into the private functions of the GPIO library and use the gpiochip_* functions instead. Only include and since we are both producers and consumers in this case.
